HENRY E. AI-IL AND CONSTANTINE 1?. MAVRELIS, OF SHEFFIELD, PENNSYLVANIA.

LENS.

Application filed August 3, 1922. Serial No. 579,417.

lie it known that we, HENRY E. Ant and CoNs'rAN'rINn P. Mavnnnrs, citizens of the United States, residing at Sheffield, in the county of Warren and State of Pennsylvania. have invented new and useful Im provements in Lenses, of which the following is a specification.

This invention relates to non-glare devices for head-lamps for motor vehicles and the like, the general object of the invention being to provide means for directing the rays of light downwardly and preventing the rays from blinding other motorists or other persons on the road.

Another object of the invention is to make the entire front face of the device of transparent material, portions of which are plain and portions frosted, with. the frosted parts covering the plain parts so as to prevent a glare of light from the plain parts.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing our invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a front view of the invention.

Figure 2 is a section on line 2 2 of Figure 1.

Figure 3 is a section on line 3 of Figure 2.

Figure 4 is a bottom plan view.

Figures 5 and 6 are detail views.

In these views, 1 indicates a transparent plate of circular shape. This plate has horizontal strips of frosted design thereon as shown at 2 which are spaced apart to leave strips 3 of plain glass. A cylindrical rim A is provided with a flange 5 and the plate 1 is held against this flange by the clips 6. A gasket 7 may be placed between the plate and the flange. The rim 4: supports strips 8 of glass or the like which are frosted and which are inclinedly arranged and extend transversely across the rim. The strips are so placed that they will prevent the rays of ward ly.

light from passing straight from the plain strips 3 but will deflect such rays down- The inner edge of each strip 8 is about on a level with the upper edge of the plain strip 3. These strips 8 are held in guideways 9 formed on the inner surface of the cylindrical rim. The. under part of this rim is cut away as shown at 1.0 so that the rays of light can pass through the same directly upon the ground and thus light the road close to the vehicle.

The device can be supported in a lamp in the ordinary or any desired manner.

The entire front of the device is transparent but all the exposed parts are of frosted design so that while the maximum degree of light will be given by the device there is no danger of the device blinding other drivers or other persons on the road.

It is thought from the foregoing description that the advantages and novel features of our invention will be readily apparent.

lVe desire it to be understood that we may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

Having thus described our invention whatwe claim is 1. A non-glare device comprising a lens formed of alternately plain and frosted strips and inclined shields for the plain strips.

2. A non-glare device comprising a cylindrical rim having a flange, a transparent plate of circular form, means for holding the same on the flange, said plate having frosted strips thereon spaced apart to form plain parts and inclined strips of transparent material held in the rim in front of the plain strips.

3. A non-glare device comprising a cylindrical rim having a flange a transparent plate of circular form, means for holding the plate on the flange, said plate having frosted strips thereon and plain strips and inclined frosted strips of glass carried by the rim in front of the plain strips.

In testimony whereof we affix our signatures.

HENRY E. AHL. CONSTANTINE P. MAVRELIS.
